Analysis of the Impact of the Post-Consumer Film Waste Scenario and the Source of Electricity on the Harmfulness of the Mass Packaging Process.

Life cycle analysis (LCA) is a popular tool for determining the environmental impacts of a product in use. The aim of this study is to carry out a life cycle analysis, gate-to-gate, of a mass packaging process using a polyethylene shrinking film with a focus on energy consumption, raw material use and associated emissions, and film post-consumer disposal scenarios. Two different scenarios for the disposal of the shrinking film used in the packaging process were analyzed, namely recycling and landfills.

IMPROVEMENT OF THE MODEL OF PREVENTION OF MALIGNANT NEOPLASM OF THE GASTRIC.

The fight against malignant neoplasms is one of the most important problems of health care in Ukraine; its relevance is due to the continuous growth of oncological morbidity in the population, the complexity of timely diagnosis and treatment, high cost, as well as quite high levels of disability and mortality of such patients. Gastric cancer, which remains one of the most common and deadly neoplasms in the world, occupies one of the leading positions among cancer. Aim - scientifically substantiate and develop a model for improving the organization of prevention of malignant neoplasms of the gastric.

Borylated cyclobutanes thermal [2 + 2]-cycloaddition.

A one-step approach to borylated cyclobutanes from amides of carboxylic acids and vinyl boronates is elaborated. The reaction proceeds the thermal [2 + 2]-cycloaddition of -generated keteniminium salts.

Psammophytes Stapf and Host Are Sensitive to Soil Flooding.

While morphological and functional traits enable hydrophytes to survive under waterlogging and partial or complete submergence, the data on responses of psammophytes-sand plants-to flooding are very limited. We analyzed the effect of 5- and 10-day soil flooding on the photosynthetic apparatus and the synthesis of alcohol dehydrogenase (ADH), heat shock proteins 70 (HSP70), and ethylene in seedlings of psammophytes and using electron microscopy, chlorophyll fluorescence induction, and biochemical methods. It was found that seedlings growing under soil flooding differed from those growing in stationary conditions with such traits as chloroplast ultrastructure, pigment content, chlorophyll fluorescence induction, and the dynamics of ADH, HSP, and ethylene synthesis.
